Слайд 2

Protozoans (amoeba, paramecium)
They have contractive vacuole to remove wastes, or diffusion

is another way to remove waste(CO2) from the cell.

Слайд 3

Flatworms(planaria)
Flatworms use flame cells to excrete wastes. Many flame cells come

together to form a net of tubules. Tubule collect wastes and excrete them through pores.

Слайд 4

Segmented worms (earthworm)
Segmented worms have net of ciliated tubules called nephridia.

They remove wastes outside through the pores.

Слайд 5

Crustaceans(crayfish, lobster)
Excretory organs of crustaceans are green glands.

Слайд 6

Insects(ant, bee)
Insects use Malpighian tubules

Слайд 7

Arachnida(spider)
Coxal glands and Malpighian tubules

Слайд 8

Fish
They use gills to excrete CO2(carbon dioxide) and kidneys to remove

ammonia.

Слайд 9

Amphibians (frog)
Adult amphibians use lung and skin to excrete CO2, and

oval kidney to remove ammonia

Слайд 10

Reptiles(lizards and crocodiles) and birds
They remove uric acid from kidney

through cloaca, and lungs to remove CO2
